Abstract
Description
Die Erfindung betrifft ein Werkzeug zum Glätten von Ober= flächen mit einer von einer Basis gebildeten, im wesent= lichen ebenen Arbeitsfläche und einem an der dieser Arbeits= fläche abgewendeten Seite dieser Basis angeordneten Hand= griff.The invention relates to a tool for smoothing surfaces with a substantially flat working surface formed by a base and a handle arranged on the side of this base facing away from this working surface.
Solche Werkzeuge werden zum Glätten von Oberflächen aller Art, z.B. als Schleif- und Polierwerkzeuge, als Raspeln, aber auch zum Verreiben von Überzugsmaterialien, wie Mörtel, Kitt usw. benutzt.Such tools are used for smoothing surfaces of all kinds, e.g. used as grinding and polishing tools, as rasps, but also for rubbing coating materials such as mortar, putty, etc.
Aufgabe. der Erfindung ist es, den Handgriff eines solchen Werkzeuges so zu gestalten, daß die Finger der Hand des Benutzers möglichst bequem an der hiefür bestimmten Seite der Werkzeugbasis anliegen können, so daß der Gefahr einer Verkrampfung der Finger auch bei langzeitiger ununter= brochener Benutzung des Werkzeuges zuverlässig vorgebeugt wird.Task. The invention is to design the handle of such a tool so that the fingers of the user's hand can rest as comfortably as possible on the side of the tool base intended for this, so that the risk of cramping the fingers even with long-term uninterrupted use of the tool is reliably prevented.
Weiters ist Aufgabe der Erfindung eine Gestaltung des Hand= griffes, die es ermöglicht, das Werkzeug beliebig, nämlich in kreisende oder hin- und hergehende Bewegungen zu ver= setzen, wobei dieses Werkzeug im einen wie im anderen Fall absolut zuverlässig und gleichermaßen günstig von der Hand erfaßt und gehalten werden kann, ohne daß dadurch die Fin= germuskeln der Gefahr einer vorzeitigen Ermüdung unterliegen.Furthermore, it is an object of the invention to design the handle which enables the tool to be moved arbitrarily, namely in circular or reciprocating movements, this tool being absolutely reliable and equally inexpensive in one way and the other The hand can be grasped and held without the fingers being subject to the risk of premature fatigue.
Erfindungsgemäß ist zur Lösung dieser Aufgaben vorgesehen, daß der Handgriff als ein an der Basis ausmittig ange= ordneter, länglich gestalteter, zwischen den Daumen und den Zeigefinger einer Hand passender Vorsprung ausgebildet ist.According to the invention to solve these problems it is provided that the handle as an eccentric at the base = orderly, elongated projection, which is formed between the thumb and the index finger of a hand.
Die Erfindung beruht nämlich auf der Erkenntnis, daß dank dieser Ausbildung und Anordnung des Handgriffes sämtliche Finger der Hand des Benutzers während der Werkzeugbenutzung ausgestreckt bleiben können, so daß die Gefahr einer Ver= krampfung der Finger dadurch von vornherein weitgehend beseitigt ist.The invention is based on the knowledge that thanks to this design and arrangement of the handle all fingers of the hand of the user can remain stretched while using the tool, so that the risk of cramping the fingers is largely eliminated from the outset.
Zur Verbesserung der Griffigkeit des Werkzeuges weist der Vorsprung nach einer bevorzugten Ausführungsform des Er= findungsgegenstandes konkav ausgerundete Flanken und/oder Stirnseiten auf, um dem Daumen und dem Zeigefinger günstig gestaltete Anlageflächen zu bieten.To improve the grip of the tool, the projection has, according to a preferred embodiment of the invention, concavely rounded flanks and / or end faces, in order to offer the thumb and the index finger favorably designed contact surfaces.
Um auch den übrigen Fingern der Hand eine solche gute Anlagefläche zur Verfügung zu stellen, ist zweckmäßiger= weise der Vorsprung längs einer Seitenkante eines gegenüber der plattenförmigen Basis erhöhten, mittig an der Oberseite dieser Basis angeordneten Sockels verlaufend angeordnet, an dessen dem Vorsprung benachbarter Flanke der Daumen und an dessen an den Vorsprung anschließende Oberseite dieses Sockels die übrigen Finger der Hand anlegbar sind. Die auf der Oberseite dieses Sockels anlegbaren Finger vermögen somit gemeinsam mit Daumen und Zeigefinger bequem, nämlich in gestrecktem Zustand, Druck auf das Werkzeug auszuüben.In order to make such a good contact surface available to the other fingers of the hand as well, the projection is expediently arranged along a side edge of a base which is raised in relation to the plate-shaped base and arranged centrally on the upper side of this base, on the flank of which is adjacent to the projection Thumb and the other fingers of the hand can be placed on the top of this base adjoining the projection. The fingers that can be placed on the top of this base can thus comfortably exert pressure on the tool together with the thumb and forefinger, namely in the stretched state.
Damit - der Gestaltung der menschlichen Hand entsprechend - der Daumen in einer tieferen Ebene am Handgriff angelegt werden kann als die übrigen Finger, ist weiters vorgesehen, daß der Vorsprung vom Sockel ausgehend unter einem spitzen Winkel von vorzugsweise etwa 450 schräg aufwärts und aus= wärts von der Basis ausragt.Furthermore, so that the thumb can be placed on the handle in a lower plane than the other fingers, in accordance with the design of the human hand, that the projection from the base, starting at an acute angle of preferably approximately 45 0 obliquely upward and protrudes from Windwärts = from the base.
Zur weiteren Verbesserung der Griffigkeit und Handhabung des Werkzeuges ist es vorteilhaft, wenn die als Auflager , für die Finger der Hand dienende Oberseite des Sockels an dessen drei vorsprungfreien Seitenkanten den unteren Teil des Sockels mit einer Randleiste überragt.To further improve the grip and handling of the tool, it is advantageous if the upper side of the base, which serves as a support for the fingers of the hand, projects beyond the lower part of the base with an edge strip on its three projection-free side edges.
Schließlich ist es für die Stellung der Hand, die das Werk= zeug hält und benutzt, auch noch von Vorteil, wenn die Oberseite des Sockels schräg aufwärts gegen den von dieser Oberseite ausragenden Vorsprung ansteigend verläuft.Finally, it is also advantageous for the position of the hand that holds and uses the tool if the top of the base rises obliquely upwards against the protrusion protruding from this top.
Grundsätzlich kann das Werkzeug zwar aus beliebigem Material gefertigt werden, doch hat es sich als empfehlenswert erwie= sen, das Werkzeug einstückig, aus einem nachgiebigen, vor= zugsweise elastisch nachgiebigen, Material, z.B. einem Kunststoff, wie Polyurethan, herzustellen. Ein solches Werkzeug vermag sich besonders günstig verschiedenerlei Oberflächengestaltungen der zu bearbeitenden Werkstücke oder Bauteile anzupassen, wobei hinzukommt, daß dank der erfindungsgemäßen Ausbildung des Handgriffes mit sämtlichen Fingern des Benutzers, also praktisch mit der ganzen Hand, eine jeweils wünschenswerte Verformung und Anpassung des nachgiebigen Werkzeuges zustandegebracht werden kann.In principle, the tool can be made from any material, but it has proven to be advisable to make the tool in one piece, from a flexible, preferably elastically flexible, material, e.g. a plastic, such as polyurethane. Such a tool is particularly suitable for adapting various surface designs of the workpieces or components to be machined, with the additional fact that thanks to the design of the handle according to the invention with all fingers of the user, i.e. practically with the whole hand, a desirable deformation and adaptation of the resilient tool has been brought about can be.
Das in der einzigen Zeichnungsfigur beispielsweise darge= stellte und nachstehend erläuterte Werkzeug besitzt eine etwa rechteckförmige und plattenförmige Basis 1 mit einer im wesentlichen ebenen Arbeitsfläche 2, an der bedarfs= weise in irgend einer an sich bekannten und für vorliegende Erfindung unwesentlichen Art und Weise, z.B. durch Haftung, Klebung oder mittels Befestigungsorganen mechanisch, ein Schleif- oder Poliermaterial 3 befestigt werden kann.The tool shown in the single drawing figure, for example, and explained below, has an approximately rectangular and plate-shaped base 1 with an essentially flat working
An der der Arbeitsfläche 2 abgewendeten Seite (Oberseite) der Basis 1 ist der Handgriff angeordnet, der im wesent= lichen als ein ausmittig, also längs einer Seitenkante, verlaufender, länglich gestalteter, zwischen den Daumen 4 und den Zeigefinger 5 einer Hand passender und hiezu mit konkav ausgebildeten Flanken 6 und Stirnseiten 7 gestalteter Vorsprung 8 ausgebildet ist. Dieser Vorsprung 8-ist längs einer Seitenkante eines gegenüber der Basis 1 erhöhten, mittig an der Oberseite dieser Basis 1 angeordneten Sockels 9 vorgesehen, an dessen gemeinsam mit dem Vorsprung 8 ge= bildeter Flanke 6 der Daumen 4 und auf dessen an diesen Vorsprung 8 anschließende Oberseite 10 die übrigen Finger 5, 11,12 und 13 der Hand des Werkzeugbenutzters anlegbar sind.On the side facing away from the work surface 2 (upper side) of the base 1, the handle is arranged, which essentially extends as an eccentric, that is to say along a side edge, extending, elongated, between the thumb 4 and the
Der Vorsprung ragt vom Sockel 9 ausgehend unter einem spitzen Winkel α, von vorzugsweise etwa 45° schräg aufwärts und aus= wärts von der Basis 1 aus, so daß der Daumen 4 - der Aus= bildung der menschlichen Hand entsprechend - an der Flanke 6 in einer tieferen Ebene anliegen kann als die übrigen Finger 5, 11, 12 und 13.The projection protrudes from the
Die als Auflager für diese übrigen Finger dienende Oberseite 10 des Sockels 9 überragt an dessen drei vorsprungfreien Seitenkanten den unteren Teil des Sockels 9 mit einer Rand= leiste 14, die zur Verbesserung der Griffigkeit des Sockels 9 für diese übrigen Finger 5, 11, 12 und 13 dient.The
Die Oberseite 10 des Sockels 9 steigt gegen den von dieser Oberseite 10 ausragenden Vorsprung 8 mit einem Winkel β von etwa 5 bis 10° schräg aufwärts an. Auch diese Gestaltung verbessert die Handhabung des Werkzeuges, indem sie auf die normale Stellung der menschlichen Hand Rücksicht nimmt.The
